Question

question 21
choose the action that is associated with protecting natural resources sustainably.
buffer zones are created near a coastal town to address sea level rise.
a city votes to increase mass transit options.
family planning resources are made more freely available.
farmers practice erosion control.

Explanation:

Increasing mass - transit options reduces reliance on individual cars, which in turn decreases fuel consumption and emissions, conserving natural resources like fossil fuels. Buffer zones are mainly for flood - protection, family planning is related to population control, and erosion control is about soil conservation but not directly about conserving natural resources in the context of energy and fuel.

Answer:

A city votes to increase mass transit options.
